From my understanding Breville and Sage are the same products just under a different name so that makes sense.
I used to work at Best Buy and I’d say considering the volume of Breville Barista units sold compared to other espresso machines they had a remarkably low return rate. I’d see lower volume products returned more often for other appliance categories.
Running on Windows 11 with a 6900XT and Vulkan and DX11 look effectively identical as far as I can tell but Vulkan runs a lot faster and doesn’t stutter when loading a new area.
Unfortunately though it tends to crash on tab out which means I need to use DX11 because I play with friends.
